Have More Room for Subs!


The PM500X2 is a 500 Watt 2-channel amplifier with high dynamic power using Class-a/b technology and a conformal coated pc board designed for motorsport and marine applications.

The PM500X2 is an excellent way to PUNCH up your sound system without monopolizing your entire trunk – that way you have more room for subs! With its massive output stage, this amplifier is best suited for driving a pair of 8-ohm SVC subwoofers or four 2-ohm DVC subwoofers. Remember to utilize the recommended power and speaker cables to optimize power delivery.
